# This is the original Python 2.7 build file, used in building GlowScript

# according to the scheme described in docs/MakingNewVersion.txt.

# A more sophisticated build program is build_cli.py contributed by Iblis Lin.

# The main runtime library glow.X.Y.min.js apparently is too large to use

# in Jupyter VPython, so this program in addition to producing glow.X.Y.min.js

# also produces the two pieces glow.X.Ya.min.js and glow.X.Yb.min.js used in

# Jupyter VPython.

"""This python program converts various parts of glowscript from the most

convenient format for modification into the most convenient format for

deployment.

* Take shaders from shaders/*.shader and combine them into lib/glow/shaders.gen.js

TODO

* Come up with a less painful model for development than running this after every change

* Combine and minify lib/*.js into ide.min.js, run.min.js, and embed.min.js
